    Portuguese I1 - How common is it?

    Hi friends, I put my AncestryDNA data into Mosley's calculator and I ended up with I2a2a2~1. https://pastebin.com/hmQWYWvT (My data I put in).

    How common is this, is Mosley's accurate, and should I get my Y dna tested somewhere else for more accurate results?

    Eupedia has I1 in Portugal at 2%, but if the Morley calculator is telling you that you're I2a2a2~1, it's most likely that you're not I1 and actually I2. In that case, Eupedia has percentage of I2/I2a at 1.5% with I2b at 3% - see here https://www.eupedia.com/europe/europ...logroups.shtml

    The Morley tool generally works well and is a nice utility, but uses a reference tree from 2013 and hasn't been updated since, so sometimes it's a bit off but generally it gives the appropriate result. You could try the YSEQ cladefinder which uses the more up to date YFull tree and see if you get the same result https://cladefinder.yseq.net/

    The AncestryDNA test includes a small number of Y-SNPs - in some cases it's possible to get a decent amount of subclades downstream, while for others it won't give much more than a basic haplogroup. To be fair to Ancestry, it's primarily an autosomal DNA test and they don't market their test as including Y-DNA, so think of it as bonus data. As for accurate, I find that when most people say accurate, then actually mean precise. So if the Morley and YSEQ cladefinder both tell you that you're I2, that's likely to be accurate. But if you want more detailed data on which subclade of I2 you fall under, you may need to take a Y-DNA test that's specifically designed for that (which the AncestryDNA test isn't).

    Where are you from in Portugal? My maternal grandfather had Island Portuguese paternal origin and he was I1. In his case it could be a Visigothic line or remnant of the Dutch/Flemish who were involved in the colonization of the islands.

    those damn Vikings got around. my paternal haplogroup is I1 but I have no recent ~250+ years Scandinavian ancestry. Even Sicily has about 5% I1 Y haplogroup.

    I've made a brutal mistake. It's actually I1a2a2. Check the photograph in the link. I also get I-S2078 in cladefinder. http://prntscr.com/ushjvu

    Northern Portugal. Montalegre, Vila Real, Tras os Montes to be exact.

    Morley predictor uses a rather old ISOGG tree and I1a2a2~1 (I1-L41) wouldn't be accurate. It looks like Morley predicts you to be I1-M253 right now. If you're interested in really figuring out which haplogroup your Y-chromosome falls under I would recommend Y-DNA testing at YSEQ or FTDNA, etc.

    Hmm okay. Do you think it is accurate in saying im part of I1-M253?

    It's probably fairly accurate, you're positive for M253 and several of the phyloequivalents, I've yet to see a modern I-M170 that's positive for only some of those and not all of them.

    If you want to really confirm it the best way is a Y-DNA test.
